IMPROVED BRICK-MAGHINE.

To ALL wH'oM 1T MAY odNcEaN:

' Be it known that I, SAMUEL Grssmenn, of Allegheny City, in the countyof Allegheny, and State of Pennsylvania, have invented a new and usefulImprovement in Brick-Ma'chines; and I do hereby declare the following tobe a full and correct description of the same, s'uiicient to enableothers skilled in'the art to which my invention appertains tofullyu'nderstand and construct the same, reference being had to theaccompanying t drawings, which make part of this specification, and inwhicht Figure lis a plan or top view of my improved brick-machine.

Figure 2 is la bottom view of the same; and

Figure 3 is a sideelevation of the same, the hopper and knives not beingshown.

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature of my invention consists in a novel mechanism by means ofwhich the moulds are automatically pushed up to` and under the hopper,one by one, to be filled, and are pushed along until-they are receivedat the vopposite end of the hopper. i

y A, in the drawings', may represent the cylindrical hopper, through thecentre of which theshaft B passes. This shaft -is provided with a set ofgrinding-knives, C,'l1aving fa. thick rounded back and a thin edge, andset obliquely on the shaft 4so as to crush the clay between themselvesand the stationary knives D, which are secured at one end to the innerside of the hopper, and at the other end to a sleeve on the shaft B, asshown in iig. 4. Between the vstationary knives D and the bottom E ofthe hopper A, is a'set of fillers, E, consisting of blades setobliquely-onthe shaft B, their -lower edges passing close over thebottom E of the hopper, which is provided with a square opening, e,which is not quite as wide as the moulds d, so as to prevent the claywhich is pressed down in thed'moulds from scraping down the sand fromtheir sides, 'which would be the case if the4 opening e were as wide asthe moulds themselves. Gis the rollerway for the moulds, formed underthe bottom plate of the' hopper, land consisting of the bottom b and thesides c.v 4For a distance under the hopper and under i the openinge, thesides and bottom of the roller-way G are exsected, and rollers g placedin the openings, which allow the moulds to pass along-more easily thanif the bottom were a mere board, and also prevents the roller-way -Gfrom being clogged up, any clay falling outside of the moulds beingenabled to'fall through the openings between the rollers g. p Theroller-way G extends on both sids of the hopper, 'and forms on one end aplatform, H, with ,an extension, I, 'at right angles with the platformH. Each of these platforms husa slot, t and e', in which blooksj and cmove. v Blockj serves to move the moulds d up to hopper andon to theplatform H, and is Operated by means of an arm, Z, the free end of whichis attached to alever, m, operated by means of a. pin, n, on the underside of a gear-wheel, o, on the shaft B. This wheel o gears with anotherwheel p, on a shaft,p, and gives motion to the block 7c by means of the'crank-arm k', in such manner that whenever the block k is near thefarthest end of the slot z', the block j is moved, by means of the pinn. on the wheel o and intermediate devices, the length of the'slot h,leaving thernould at the point wherey it is seized by the block c on itsreturn motion, The blockj is held in position at the farthest end of theslot 7L, and is forced to resume this position every time the pin 'n hasoperated the lever m, by means ofthe spring m', attached at one end tothe platform I, and at the other to the arm Z. The wheels o undp gear insuch n, manner that the block]I will beoperated only when the block 7cis at the farthest end of the slot z', and a mould may lie-placed infront of the block j therefor, whenever this latter has returnedto'itsnormal condition, without regard to the position of the block k. Thisfeature is illustrated in ig.- l. One mould has not yetv quite beenpushed in bythe block 7c, but another isI already in position in frontof block j to be operated upon.

It ,will be easilypunderstood that as the moulds are pushed along" bymeans of each other, their ends will be in continuous close contact withcach other und prevent any clay from falling between them, and thus clogup any part of the machinery, and should the personlwho places themoulds on the platform I, in front of block j, miss one operation oftheblocks j, k, without placing a mould, no clay will be wasted, as themoulds already in the roller-way G will remain in place, as the block 7conly moves as far as the bottom plate E of the hopper.v

i' In brick-machines in which endless belts are used to convey themoulds under the hopper, much troubleis experienced by waste of clay andclogging up of the machinery, when the moulds are not placed with theutmost care and eontiguensy on the endless belt, for if the operatorshould emit to piace a. mould close to the preceding one, the clay fromthe hopper vwili fall between them and on the belt.

Having thus described my invention, whatclaim as new, sind desire tosecure by Letters Patent, is-

1. The device for moving the mould, on to" the rolier-wny G, consistingof the erm l, held bynsp'ring, m-, lever m, pin n, on the gear-wheel o,and block j, moving in the slot substantially as described.

2. The device for moving'the moulds under the hopper, consisting of thegeur-wheelp, operated bythegear-wheelo, arm 1c', and block k, moving inthe siot z', substantially as described.

3. In combination with the above, I 4claim the gear-wheel o, shaft B,grinding-*knives C, stationary knives D, and llers F, in the hopper A, snbstantially as and for the pdrposes described.

' 4. '.lhe roller-way G, ipeovided with openings and rollers g and g',substantially as and for the pnipcvseV described.

The above specification of'my improvement-in brick-machines, igned this26th day of September, y1867.4
